Vet the carrier without leaving the email.
Highlight an MC or DOT number in Gmail, click the badge, and a side panel opens with operating authority, insurance on file, safety scores, and the specific reasons this carrier is or is not risky — straight from public FMCSA data.
Works in Gmail and Outlook on the web. Right-click lookup anywhere else.

Highlight the number. That's the whole workflow.
No tab, no login, no copy-paste into SAFER. The panel opens beside the email with the record already pulled — and when the record is bad, it says so before you send the rate con.
Afternoon — we've got a 53' dry van empty in Laredo tomorrow morning and can cover your Atlanta load.
We run under MC# 5551234 / DOT# 4442211 — Summit Line Logistics. What's it paying all-in?
- No active operating authority
- Insurance on file ($0) below required ($750,000)
- Authority granted less than 6 months ago
- Phone number shared with 4 other carriers in FMCSA records
Illustrative — the carrier above is fictional.
Everybody knows they should check. Nobody has three tabs to spare.
An MC number lands in your inbox at 4:40 on a Friday with a truck ninety minutes from the shipper. Checking it properly means SAFER in one tab, Licensing & Insurance in another, and a BASIC lookup in a third — so under cover pressure, most brokers glance at the authority status, decide it looks fine, and tender the load.
CarrierVet collapses those three tabs into a highlight. The lookup happens where the MC number already is: in the email.
Three ways to start a lookup.
Install it and it works. There is no setup step, no API key to paste, and nothing to connect.
Highlight an MC or DOT number
In Gmail or Outlook on the web, select the number in a carrier's email. A badge appears over the selection — click it and the profile opens in the side panel.
Right-click on any site
Select an MC or DOT number anywhere — a load board, a rate con, a PDF preview — and choose "Vet carrier" from the context menu.
Type it into the panel
Open the side panel and search an MC number, a DOT number, or a company name directly. No email required.
Auto-highlight works out of the box on Gmail (mail.google.com) and Outlook on the web (outlook.office.com, outlook.live.com). Everywhere else is right-click, or opt in to all sites in the extension’s options.
A carrier that clears, and the same lookup on a shell.
The left-hand carrier is fourteen years into its authority with clean insurance and no overlap with anyone else. The right-hand one has twenty-eight trucks under an authority that is four months old, two insurance cancellations, and a phone number that appears on four other carriers’ FMCSA filings. Both look identical in an email.
- Authority granted less than 6 months ago
- 2 insurance cancellations in the last 36 months
- New authority with an unusually large fleet — possible reincarnated carrier
- Phone number shared with 4 other carriers in FMCSA records
- Email address shared with 6 other carriers in FMCSA records
Both carriers above are fictional and the MC numbers are placeholders. We do not print a real MC number next to a risk verdict.
What you get, per carrier.
Every field below is click-to-copy where it makes sense — the point is that the carrier packet fills itself while you read.

Contact
Authority & insurance
Safety
Risk factors
Cross-checks
21 rules, and it shows its work.
5 of the rules are critical: no active operating authority, an active out-of-service order, an unsatisfactory safety rating, insurance filed below the amount the authority requires, or FMCSA flagging the entity as not allowed to operate. Any one of them forces a High rating on its own. The other 16 are weighted minor findings — new authority, shared contact details, insurance cancellations, BASIC scores over the intervention threshold — and a weighted total of two or more points lands the carrier at Medium.
You always see the factors, never just a number. A carrier can be High-risk and still be the right truck for the load — that is your call to make, and you should be able to see exactly what you are overriding. Every rule is written out in plain English here.
Where the data comes from, and how old it is.
All of it is public FMCSA data. Some of it is live; some of it is a month old, because that is how often FMCSA publishes it. You should know which is which before you lean on a field.
FMCSA QCMobile API
Operating authority, safety rating, crash history, BASIC scores, cargo classes
FMCSA Licensing & Insurance (L&I)
Insurer name, policy effective date, insurance cancellations, authority grant and revocation history
FMCSA Company Census
Contact details, address, power units, drivers, reported mileage
FMCSA SMS inspection & violation files
Peer-group percentiles and violation rates behind the BASIC scores
FMCSA stopped publishing property-carrier SMS percentiles in 2017. The percentiles CarrierVet shows are computed from FMCSA's public inspection and violation files against peer carriers with a similar inspection count. They approximate FMCSA's methodology — they are not the official score, and the panel labels them as such.
The only thing we see is the number you look up.
When you vet a carrier, the MC number, DOT number, or company name goes to Keelway and a profile comes back. That is the whole exchange. The content of your email, the page you are on, the sender’s address, your subject lines and your customer names never leave your browser. There is no account, so there is no profile of you to build, and the extension does not track your browsing.

What CarrierVet does not do.
You are going to find these out in the first ten minutes anyway. You may as well find out now.
Chromium only
Chrome, Edge, Brave and Arc. The extension uses the Chrome side panel API, so Firefox and Safari are not supported.
Auto-highlight is Gmail and Outlook
The badge over a selected number appears on mail.google.com, outlook.office.com and outlook.live.com. Everywhere else — load boards, rate cons, carrier websites — you right-click and choose “Vet carrier”, or opt in to all sites in the options.
A name search returns the top match
Search by company name and you get the single best match, not a list to pick from. When two carriers share a similar name, search the MC or DOT number instead.
No AI summary yet
The panel has an AI summary button behind a “Pro — coming soon” badge. It is not available today, and we would rather say so than let you find a disabled button.
Percentiles are an approximation
FMCSA stopped publishing property-carrier SMS percentiles in 2017. Ours are computed from the public input files against peer carriers with a similar inspection count, and the panel labels them that way.
Carriers only
No broker bond checks, no shipper screening. Those live in Freight Check, a separate Keelway extension. CarrierVet does one job.
CarrierVet checks one carrier. Keelway checks the whole inbox.
Spot-checking has a ceiling. You post a load, forty carriers reply, and you are not going to highlight forty MC numbers — you are going to vet the three you like and take the cheapest of those. The one you did not vet is the one that re-brokers the load.
The Keelway platform reads every reply to a posted load, vets each carrier against the same FMCSA data and the same risk rules you see in the extension, ranks them by trust, rate and history, and drafts the reply in your voice. It is $799 a month, flat, with no per-seat pricing — the carrier check on every reply is in that core plan, not an add-on. Fraud Shield, at $199/mo, is the deeper layer on top: carriers that rebranded after a bad MC, fake-MC quotes, look-alike domains, and rate confirmations that got intercepted.
Nothing about that requires you to stop using CarrierVet, and CarrierVet stays free either way. Watch the platform demo if you want to see it work on a real inbox.
